Monocular Occipital Temporal Crescent Syndrome also known Temporal crescent syndrome, which occurs from a lesion in the anterior occipital cortex, however, is an exception to this rule. Temporal crescent syndrome presents as a monocular loss of a crescent shape visual field in the temporal and peripheral vision contralateral to the lesion.
This is a rare pattern of vision loss where one eye is missing a thin crescent of sight on the far-outside (temporal) edge of its visual field. Strangely, the problem is not in the eye itself. It comes from damage in the opposite (contralateral) occipital lobe—the very front tip of the brain’s primary vision area (the anterior striate cortex), which maps that outer edge of vision. Because only that thin outer map is hurt, the rest of your vision can look normal. PubMed Each eye has a small slice of far-peripheral vision that only that eye can see (beyond where the two eyes overlap). That one-eye-only slice is called the temporal crescent. It projects to a specific spot at the front of the primary visual cortex. Damage there causes a monocular temporal crescent defect, even though the trouble is in the brain. AAO This peculiar finding often escapes standard 24-2 or 30-2 automated visual field tests, which only check the central 24–30 degrees. It is best revealed by kinetic perimetry (e.g., Goldmann) or wide-field testing.
What this name really means
Monocular = only in one eye (not both).
Occipital = related to the occipital lobe at the back of the brain, where we “see.”
Temporal crescent = the far outer edge of the side vision on one side of one eye (the “temporal” side). This outer rim of vision starts beyond about 60° from what you are looking at and may reach 90–100° at the extreme edge. EyeWikiReview of Optometry
Syndrome = a pattern of findings that tend to occur together.
This is a rare problem where only one eye loses a thin crescent of far-out side vision on the temporal (outer) side, while central vision stays normal. The cause is not the eye itself, but a small, precise spot in the opposite occipital lobe (the brain’s visual cortex) that maps the most peripheral vision of that eye. It is one of the few times a retro-chiasmal (behind the optic chiasm) brain lesion makes a monocular field defect. PubMed+1
Your far-outer temporal vision in each eye is seen only by that eye (there is no overlap with the other eye). That special rim—called the temporal crescent—is processed in the front edge of the visual cortex on the opposite side of the brain (for example, left occipital cortex controls the right eye’s temporal crescent). This area is tiny—about the most anterior 6–10% of striate cortex—and is monocular (it gets input only from the far nasal retina of the opposite eye). A small injury there removes that thin rim of vision in just one eye. PMC
It is uncommon and easy to miss because most clinic visual-field tests check only the central 24–30°. People may notice little or nothing because the missing part is far out to the side. However, the cause (stroke, bleed, tumor, malformation, infection, etc.) can be serious, so brain imaging is important when it appears suddenly. EyeWiki
Types (simple classification)
Isolated “missing temporal crescent”
Only the crescent is gone in one eye. Central vision is fine. This points to a small lesion in the contralateral anterior occipital cortex (near the parieto-occipital sulcus). PubMedScienceDirect
“Preserved temporal crescent” within a larger hemianopia
In some homonymous hemianopias, the temporal crescent is spared because of how the visual cortex is supplied by several arteries. Seeing this pattern often suggests occipital lobe ischemia with a small part of cortex still working. EyeWiki
Congenital vs. acquired
Congenital occipital defects can involve or spare the crescent and may cause little or no complaint.
Acquired cases (like stroke or bleed) more often cause a new, noticed field change. EyeWiki
Causes
Key idea: the “what” is one-eye temporal rim vision loss; the “where” is the opposite anterior occipital cortex; the “why” is whatever damages that tiny spot.
Ischemic stroke of the occipital cortex – A small blockage in a branch of the posterior cerebral artery can injure the anterior striate cortex, removing the crescent. PubMed
Intracerebral hemorrhage – A small bleed in the anterior occipital lobe can abruptly erase the crescent. EyeWiki
Arteriovenous malformation (AVM) – A tangle of abnormal vessels in the medial anterior visual cortex can compress or steal blood from that area. EyeWiki
Cavernous malformation / vascular anomaly – Microscopic blood-vessel clusters can leak or press on the cortex. (Grouped under vascular malformations.) EyeWiki
Glioependymal cyst near the lateral ventricle – A cyst can push on pathways to the anterior visual cortex and cause the crescent defect. The Journal of Neurosurgery
Brain tumor (e.g., glioma) – A slowly growing mass in that cortical strip may selectively wipe out the crescent. EyeWiki
Creutzfeldt–Jakob disease (CJD) – Rarely, prion-related cortical damage can produce the pattern. EyeWiki
Peripartum hypertension–related ischemia – Blood-pressure spikes around delivery have been linked to this field defect. EyeWiki
Hemorrhagic infarction near the parieto-occipital sulcus during seizures – Seizure-related vascular changes can injure that cortex. EyeWiki
Transient hypotension (low blood pressure) – Brief low perfusion of the anterior occipital cortex has been reported to cause a temporary crescent defect. www.elsevier.com
Occipital lobe contusion (head trauma) – A blow to the back of the head can bruise the exact cortical strip. (Mechanism parallels other focal cortical injuries.)
Posterior reversible encephalopathy syndrome (PRES) – Edema in posterior brain regions may transiently affect the crescent area.
Migraine aura (rare cause) – Pure crescent-only loss from embolus is unlikely; when isolated, rare causes such as migraine or AVM are more plausible. PMC
Infectious encephalitis – Infection-related inflammation of the occipital cortex can involve the crescent region. (Fits the “infectious” etiologies noted in case series.) EyeWiki
Demyelinating disease (e.g., MS) – Occipital plaques can, in theory, affect this tiny representation, though it is uncommon.
Post-operative occipital injury – After neurosurgery near the parieto-occipital area, a small infarct could produce the defect.
Cortical venous thrombosis – Clotting of cortical veins draining the anterior occipital lobe can cause localized edema/infarction.
Radiation-induced cortical injury – Focused radiation to posterior brain can later damage the anterior striate cortex.
Cortical metastasis – A small metastatic deposit in the anterior calcarine region may selectively impair the crescent map.
Developmental cortical malformation – Abnormal formation of cortex (congenital) can include or spare the crescent and may be found incidentally. EyeWiki EyeWiki
Symptoms
Nothing obvious – Many people notice no problem because the loss is at the extreme edge of side vision and the other eye covers that area in daily life. EyeWiki
“Something missing” at the far outer edge when one eye is tested alone (for example, during an eye exam).
Trouble catching fast-moving objects that appear suddenly from the very side on the affected side when using that eye alone.
Occasional near-misses with objects at the edge (doorframes, wing-mirrors) when the other eye is covered.
Feeling that the room is slightly “narrower” on one side when one eye is closed.
No blur and no central blind spot – reading, faces, and central tasks stay clear.
No shimmering zig-zags unless migraine is the underlying cause (then there may be aura).
New headache or neurologic symptoms (weakness, numbness, speech change) if stroke or bleed is the cause—these are red flags.
Sudden onset if the cause is a bleed or infarct; gradual if a tumor or AVM is growing slowly. EyeWiki
Short-lived symptoms if due to transient hypotension or PRES; symptoms may come and go. www.elsevier.com
Seizures (if the lesion irritates cortex), sometimes followed by the field change. EyeWiki
Visual snow or unusual visual sensations if encephalitis or migraine co-exists.
Anxiety about vision despite normal day-to-day tasks, because testing reveals a “gap.”
No double vision – eye movement pathways are not the problem here.
No pain in the eye – because the eye is typically healthy; the issue is in the brain.
Diagnostic tests
Start with history and bedside testing to look for a monocular, temporal-rim loss beyond ~60°. Standard office machines (24-2 or 30-2) miss this because they only test the central 24–30°. EyeWiki
Confirm with full-field kinetic perimetry (e.g., Goldmann), which can reach 90–100° temporally and draw the crescent accurately. EyeWiki
Image the brain (CT first if acute, then MRI) to find the contralateral anterior occipital lesion and the cause (bleed, infarct, AVM, tumor, etc.). EyeWiki
Use lab tests to search for the underlying condition (clotting problems, infection, inflammation, etc.).
Electrodiagnostic tests help separate eye/retina problems from brain problems (for example, VEP shows cortical function).
A) Physical exam
Monocular confrontation visual-field testing to 90°
What it is: Doctor covers one eye and uses fingers or a moving target to test the far side vision.
Why it helps: A gap appears only beyond ~60° on the temporal side of the contralateral eye.
Key point: Must be monocular and reach very far periphery; otherwise the defect is missed. Review of Optometry
Kinetic confrontation (“moving target”)
What: A bright/large object is moved in from the side until the patient first sees it.
Why: The temporal crescent is a kinetic edge; mapping the “first-seen” point draws the missing rim.
Pupil exam (RAPD check)
What: Light is moved between eyes to look for afferent defects.
Why: Normal pupils support a cortical (brain) cause rather than optic nerve disease; an RAPD would suggest front-of-the-chiasm pathology.
Dilated fundus exam with careful look at the nasal retina periphery
What: Doctor inspects the retina, especially the nasal periphery that maps to the temporal crescent.
Why: Usually normal in this syndrome; this helps rule out retinal tears/detachments as the cause of edge-of-field loss. EyeWiki
B) Manual/perimetric tests
Goldmann kinetic perimetry
What: A classic manual test that moves light targets of different sizes/brightness from the edge toward center to draw isopters.
Why: It reaches the far periphery (out to 90–100°) and can show the missing temporal crescent clearly. Use the largest stimulus at the edge of the bowl to include the crescent. EyeWiki
Octopus kinetic perimetry / full-field static programs (e.g., 60-4)
What: Automated devices with peripheral protocols beyond 60°.
Why: They can map the crescent when central programs (24-2/30-2) cannot; note that normative data are less robust in the far periphery. EyeWiki
Tangent screen / Bjerrum screen
What: A black screen and moving target to plot field points.
Why: Less common today, but can outline peripheral defects in experienced hands.
Arc perimeter (manual kinetic campimetry)
What: A movable arc with a target sliding along it.
Why: Kinetic mapping at very wide angles helps detect the rim loss.
Double simultaneous stimulation (DSS)
What: Presenting two targets at once on both sides.
Why: Helps distinguish true field loss from visual neglect/inattention, which can mimic side-field problems.
Binocular vs. monocular mapping
What: Repeating fields with both eyes open then each eye alone.
Why: Only monocular testing shows the defect; binocular fields may look normal because the other eye overlaps.
C) Laboratory & pathological tests
Complete blood count (CBC) and coagulation profile
Purpose: Look for bleeding/clotting risks (thrombocytopenia, coagulopathy) that can cause hemorrhage or infarct.
Inflammation and autoimmune markers (ESR/CRP; ANA/ANCA; antiphospholipid panel)
Purpose: Detect vasculitis or hypercoagulable states that could injure the cortex.
Infectious work-up when indicated (e.g., HIV, syphilis)
Purpose: Certain infections can cause encephalitis or vasculitis affecting the occipital cortex. (EyeWiki lists infectious etiologies among causes.) EyeWiki
Tumor assessment (e.g., serum markers) and pathology/biopsy when imaging suggests neoplasm
Purpose: Confirm a tumor or infiltrative process if suspected on MRI. (Neoplastic/infiltrative causes are reported.) EyeWiki
D) Electrodiagnostic tests
Visual evoked potentials (VEP)
What: Measures the brain’s electrical response to visual patterns.
Why: A cortical abnormality on the side opposite the missing crescent supports an occipital cause (and helps rule out retinal/optic-nerve disease).
Electroretinography (ERG)
What: Measures the retina’s electrical response.
Why: Usually normal here; a normal ERG with an abnormal field favors a brain (not retinal) origin.
Electroencephalogram (EEG)
What: Records brain waves.
Why: Looks for seizure activity when the field defect follows seizures or when cortical irritability is suspected. EyeWiki
E) Imaging tests
Head CT (non-contrast first in acute cases)
Purpose: Fast way to detect hemorrhage and large strokes causing the crescent defect; often the first test in the emergency setting. EyeWiki
Brain MRI (with DWI, FLAIR, and GRE/SWI sequences)
Purpose: Best at showing small infarcts, microbleeds, cysts, tumors, or malformations in the contralateral anterior occipital cortex. Gradient-echo/SWI is especially good for subtle hemorrhage. EyeWiki
Vascular imaging (CTA/MRA; catheter angiography for AVM)
Purpose: Finds arterial occlusion, stenosis, or AVMs feeding/draining the affected cortex; guides treatment. EyeWiki
Non-pharmacological Treatments
These focus on rehabilitation, safety, and compensation, while the medical team treats the underlying cause (stroke, tumor, AVM, etc.).
Kinetic/wide-field perimetry-guided training. Practicing with targets placed into the blind “crescent” encourages bigger, faster eye and head movements into the missing zone. This improves scanning and navigation. ScienceDirect
Systematic scanning (saccadic) training. Therapist-led programs teach left-to-right and right-to-left sweeps, fixation “stops,” and head turns to reduce near-misses and improve reading lines. RCTs show benefit, especially for mobility/QoL. SAGE JournalsScienceDirect
Peripheral (Peli) prism segments on glasses. Prisms shift images from the blind zone into seeing retina, expanding awareness; widely used for hemianopic field loss and applicable to crescent losses when oriented to the missing sector. tvst.arvojournals.orgLippincott Journals
Reading adaptations. Line guides/typoscopes, larger print, increased spacing, and e-readers with text-to-speech reduce skipping and fatigue. AAO
Mobility training & orientation therapy. Cane options, “clock-face” scanning at crossings, and safe street-edge approaches cut collision risk. ScienceDirect
Driving assessment & rehabilitation. Formal on-road screening and training teach compensatory checks; some regions require reporting/retesting. (Follow local law.) AAO
Lighting optimization. Brighter, uniform light and anti-glare strategies (hats, matte screens) improve detection of side-objects.
High-contrast & clutter reduction at home/work. Color-contrast tape on edges/steps and decluttering boost peripheral cue salience.
Head-posture coaching. Habitual micro-turn toward the blind side widens effective field during tasks.
Task-specific drills. E.g., doorway entry (pause-scan-step), supermarket aisle scanning, or sports drills (partner toss from blind side).
Visual-attention apps. Therapist-guided software can reinforce scanning; evidence is mixed but reasonable as an adjunct. University of Rochester Medical Center
Occupational therapy at the workplace. Desk/monitor setup and workflow changes reduce misses on the blind side.
Fall-prevention home visit. OT/PT checks rugs, cables, lighting, and furniture paths.
Mindfulness & stress reduction. Anxiety worsens scanning behavior; simple breathing routines can help adherence to rehab.
Sleep hygiene. Better sleep supports attention, learning, and neuroplasticity.
Exercise program. Aerobic + balance training improves overall function and stroke risk factors.
Smoking cessation support. Essential for vascular brain health; combine counseling plus pharmacotherapy if needed. AHA Journals
Blood pressure, glucose, and lipid self-management routines (home BP cuff, diet, activity logs) to prevent progression/recurrence. American College of Cardiology
Family/caregiver education. Teach loved ones how to approach and hand objects from the seeing side or after alerting the patient to scan.
Support groups & low-vision services. Community resources help with coping, devices, and legal/driver issues.
Drug Treatments
(Always individualized by your doctor; doses and timing below are typical for adults and may not fit everyone. Acute stroke drugs are time-critical.)
Alteplase (tPA) — IV thrombolytic for eligible acute ischemic stroke
Class: Fibrinolytic. Dose: 0.9 mg/kg (max 90 mg): 10% IV bolus, remainder over 60 min; usually within ≤4.5 h of onset. Purpose: Re-open the blocked artery.

Dose: 10 mg daily if LDL-C remains ≥70 on max statin. Mechanism: Blocks intestinal cholesterol absorption. Side effects: Usually mild GI. American College of CardiologyBlood-pressure medicines (examples; tailored to patient)
*Lisinopril 10–40 mg daily, Amlodipine 5–10 mg daily, Chlorthalidone 12.5–25 mg daily. Goal: ~<130/80 mmHg for most after stroke. Side effects: Cough (ACEi), ankle swelling (CCB), low potassium (thiazide). AAFPLevetiracetam — if occipital seizures coexist
Dose: Commonly 500–1500 mg twice daily (individualized). Purpose: Prevent visual auras/seizures. Side effects: Somnolence, mood changes.
Important: drug choice depends on the cause (ischemic/hemorrhagic stroke, tumor, AVM, etc.). Some conditions do not use antithrombotics. Follow specialist guidance only. AHA Journals
Dietary & Supportive Supplements
(Evidence ranges from strong to limited. Always check interactions—especially if you’re on blood thinners.)
Icosapent ethyl (EPA-only omega-3) — 2 g twice daily (with meals). Function: Lowers residual CV risk; reduced stroke in high-risk groups in large trials. Mechanism: Anti-inflammatory, triglyceride lowering, plaque stabilization. Caution: May increase AF risk in some. PMCAHA Journals
General omega-3 (fish oil EPA/DHA) — 1–2 g/day; CV data mixed; focus on oily fish weekly if possible. PMC
Coenzyme Q10 — 100–300 mg/day; antioxidant; small human/animal studies suggest neuroprotective potential; evidence still preliminary. Caution: Warfarin interaction. PubMed+1
Folate + B12 (if homocysteine high) — per labs; supports homocysteine metabolism; mixed stroke data; safe when indicated.
Magnesium — 200–400 mg/day; may aid BP and headaches; watch for diarrhea/renal issues.
Potassium (prefer food sources) — fruits/veg/legumes; helps BP; supplements only with clinician ok (can be dangerous with some meds).
Vitamin D — 1000–2000 IU/day if low; general health; stroke data mixed.
Cocoa flavanols — ~200–400 mg/day; may improve endothelial function.
Beetroot nitrate — juice or capsules; raises nitric oxide; short-term BP effects.
Psyllium fiber — 7–10 g/day; helps LDL and glycemic control.
Green tea catechins — 200–400 mg/day; antioxidant; modest BP/LDL signals.
Curcumin — 500–1000 mg/day with food; anti-inflammatory; variable absorption.
Resveratrol — 150–500 mg/day; antioxidant; human vascular data limited.
Lutein/zeaxanthin — macular support; indirect visual comfort benefits.
Ginkgo biloba — sometimes touted for brain blood flow; evidence inconsistent and bleeding risk exists—avoid with antiplatelets/anticoagulants unless your doctor approves. PMC
Regenerative / Immune-modulating” Therapies
These are investigational for stroke-related vision loss. None are standard of care for temporal crescent defects. Ask about clinical trials.
Mesenchymal stem cells (MSCs) — trials suggest safety and possible functional benefit; efficacy remains inconclusive, more RCTs needed. Delivery routes vary (IV/intra-arterial). PMC+1
Allogeneic progenitor cells (e.g., MultiStem) — randomized trials are ongoing/early; mixed signals so far. JAMA Network
Neural stem cell approaches — early-phase research exploring neurorepair and synaptic plasticity. Cell
Exosome-based therapies — preclinical; aim to deliver growth factors/miRNAs to promote repair. ScienceDirect
G-CSF (filgrastim) to mobilize endogenous stem cells — feasibility shown; functional benefits remain uncertain; side effects include leukocytosis/spleen risk. AHA JournalsScienceDirect
Erythropoietin derivatives — once promising; some trials showed no benefit and potential harm when combined with tPA; not recommended outside trials. PMC
Procedures / Surgeries
Endovascular mechanical thrombectomy (for eligible large-vessel occlusions).
Why: Pulls out the clot when a big artery is blocked; restores blood flow. Note: Patient selection and timing are strict. www.stroke.orgMicrosurgical resection of occipital/temporo-occipital tumors with mapping to protect optic radiations.
Why: Remove mass, reduce edema, and preserve vision pathways. FrontiersStereotactic radiosurgery (SRS) for selected AVMs or small tumors.
Why: Obliterate AVM nidus or control tumor growth when open surgery is risky. AHA JournalsEndovascular AVM embolization (sometimes staged, often combined with surgery/SRS).
Why: Reduce blood flow and bleeding risk; adjunct to definitive therapy. AHA JournalsAneurysm treatment (coiling, stent-assisted coiling, clipping, or bypass + occlusion for complex PCA aneurysms).
Why: Prevent rupture or relieve mass effect/embolization risk. Frontiers
The choice among these depends entirely on the underlying cause and is made by a stroke/neurosurgery–neuro-ophthalmology team.
Prevention Essentials
Keep BP under control—goal often <130/80 mmHg after stroke. American College of Cardiology

Ease off / avoid routinely:
Processed meats and high-sodium packaged foods (raise BP).
Sugary drinks/refined sweets (worsen glucose and weight).
Excess alcohol.
Trans fats and frequent deep-fried foods. PMC
FAQs
1) Is my eye diseased?
Usually no. The brain’s visual cortex is the problem, not the eye itself.
2) Why only one eye’s outer edge?
The temporal crescent is a unique sliver of vision seen by a single eye and mapped at the front of occipital cortex—so a tiny brain lesion there can affect only that crescent. PubMed
3) Can standard visual field tests miss it?
Yes. 24-2/30-2 programs test mainly the central field. Goldmann kinetic or wide-field testing is better.
4) What’s the most common cause?
A small occipital stroke (PCA territory) is a classic cause. PubMed
5) Can it improve?
Sometimes—depending on the cause and recovery. Rehab teaches the brain to compensate even if the missing patch remains. ScienceDirect
6) Are prisms useful?
Yes, peripheral prisms can shift images from the blind area into seeing retina and help awareness. tvst.arvojournals.org
7) Is surgery needed?
Only if there’s a treatable structural cause (tumor, AVM, aneurysm) or a thrombectomy is indicated for a large-vessel stroke. AHA Journalswww.stroke.org
8) Can diet help?
Diet can’t fix the defect, but Mediterranean-style eating reduces future vascular events. New England Journal of Medicine
9) Are stem cells a cure?
Not yet. Trials are ongoing; results are mixed. It’s not standard care. PMC
10) Is it safe to drive?
Depends on your overall fields and local laws. Get formal visual field testing and a driving eval. AAO
11) Will glasses fix it?
Regular lenses don’t restore missing field. Prism segments can help awareness; rehab improves scanning. tvst.arvojournals.org
12) Can it be in both eyes?
The crescent loss is monocular, but other field defects (e.g., hemianopia) can coexist bilaterally depending on the lesion.
13) Why do I feel anxious now?
Peripheral loss changes confidence. Rehab, education, and support groups help a lot.
14) Will it happen again?
Your risk depends on the cause. Control BP, lipids, diabetes; follow antithrombotic plans. AHA Journals
15) What should my family know?
Approach from the seeing side, announce items from the blind side, and encourage scan-before-step habits.
